MARINE WATER-CLOSET.

Specification of Letters Patent.

Patented Feb. 3, 1920;

Application filed. July 26, 1919. Serial No. 313,471.

with the outlet of the bowl operated by an electric motor which also operates a second pump forcing water into the bowl, the electric circuit'of the motor controlled by the action of a lever which operates a valve normally closing the outlet of the bowl so that when the valve is moved to an open position, the flushing operation isbegun;

A further object is to provide an improved construction and arrangement of a centrifugal pump in the outlet or discharge from the bowl which exerts a suction as well "as an ejecting action to, thoroughly discharge the contents of the bowl.

A further object is to provide an improved arrangement of pumps and valves, the latter manually operated by means of a lever, and the lever operating to close an electric circuit including a motor and a source of electriclty supply, the motor driving the pumps and controlling the flow of water in the flushing of the bowl.

With these and other objects in vievs the invention consists in certain novel'features of construction, and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims; g

In the accompanying drawings.-

, Figure 1 is a view in longitudinal section illustrating .our improved closet;

Fig. 2 is a top plan view;

Fig. 3 is an end view of the water closet,

' the view being taken on the section line 3-3 of Fig. 2;

-' Fig. 4'is a view, in section, of the centrlfugal pump 8, the view belng 1n section U online 4 4 of Fig. 1'; and

Fi 5 illustrates an electric diagram -'show1ng an electric circuit controlling the motor 23.-

represents a bat: or vessel-of: any sort marine water having a floor 2 therein on which the bowl 3 is supported. The bowl is provided at ts upper end with an annular water flushing chamber4 and at its lower portion with an outlet 5 normally closed by a pivoted bowl closure 6. The bowl 3 discharges into a relatively large horizontal pipe 7 communlcating at its outlet end with the center of a centrifugal pump 8, said pump discharging at its lower portion into an outlet pipe 9, a check valve 10 being located at the outlet of the pump 8 to permit a flow in one direction only. The outlet pipe 9 is provided with a sea cockll which may be closed when desired. 12 represents a gear pump having an inlet pipe 13 with a sea cook 14 therein. Be-- tween the sea cook 14 and the pump 12 any suitable form of manually operated valve 15 may be provided. WVe have'illustrated this valve as an ordinary gate valve, but any other suitable construction of valve may be utilized. r

The gear pump 12 discharges the water through a pipe 16 into the flushing chamber pivotally. supported on'the floor 2, as indi- .catcd at 24, and held in normal position by a coiled spring 25 connecting the lever 24 with the bowl 3. A link 26 connects'the lever 24 with a crank arm 27 on the bowl closure 6 so that the lever controls the operation'of the bowl closure.

g The gate valve 15, above referred to, is operated by means of a crank arm 28, to

V which a link 29 ispivotally connected, and

is provided with apin 30 engaging a cam 31 on a longitudinally movable. rod 32.

. This rod 32 is supported in a bearing bracket 33 and is connected by a link 34 with the lever 24.

35 and 36 represent electric contacts supported by and insulated from the lever 24 and boat 1 respectively. V

In Fig. 5, we illustrate a simple form .of

electric diagram which may be utilized in connection with our improved apparatus-.;

A wire 37 connects the contact 36 with one side of the motor 23. A wire 39 connects the other side of the motor with one pole of the battery 40 or other source of electricity supply, while the opposite pole of the battery is connected by the wire 38 with the contact 35.

We would call special attention tothe rotary elementlS of the centrifugal pump 8. It will be noted that the rotary element 18 comprises a series of radial blades 18, which not only cause a suction and discharge of the water, but also act as ejectorswhich force the material out through the outlet pipe by reason of physical contact so that there is little possibility of the closet becoming clogged at any point from the bowl to the out et.

The operation is as follows: When the V lever 24 is moved from its dotted line position in Fig. 1 to its fullline position, it will, through the medium of link '24, draw the closure 6 to the open position shown. the same time the lever 24, through the medium of link 3 1, rod 32, cam31, link 29 and crank arm 28, opens the gate valve .15. v This movement of the lever 24' also moves the contact againstthe contact 36 closing the electric circuit and causing the operation of the motor 23. The motor drives both of the pumps 12 and'8 through the medium of shaft 21. worm 22, worm wheel 20 and shaft 17. Water is thus sucked in through the pipe 13 by the pump 12 and forced through the pipe 16 and chamber 4L 1 into the bowl to thoroughly flush the same.

At the sametime, the centrifugal pump 8 sucks all the contentsof the bowl through the pipe 7 and discharges the same through the pipe 9 and outside of the boat.

Various slight changes may be made in the general form and arrangement of parts described without departing from the invention, and hence we do not limit ourselves to the precise details set forth but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.
